...I hate to be difficult, but the Powers That Be around here have told me I'm not supposed to give you access to https://www.caerllewys.net/.well-known/acme-challenge/r0LktXAwmlrAvw-pV8NrKJn43KLNou76ccL5sEQAfZc. Just can't do it. Nohow, no way. Can't let you have it.
Sorry, buddy, it's not my fault, I don't make the policies around here, I just have to enforce them. It's my job on the line, you know. If it's a problem, you better complain to management, down the hall.
